British Dog World- Living With Dogs

"The product which contains one per cent N-Acetyl-L-Carnosine, a naturally occurring antioxidant, is actually called Ethos Bright Eyes Drops and is said to soothe and rejuvenate tired eyes naturally. It is 100 per cent hypoallergenic and 100 per cent free of animal ingredients and was originally formulated for humans.
The fact that it is equally effective for dogs is a major plus."

"Bright Eyes is also obtainable as a powder (Vital Health Carnosine), to be dissolved in bottled water and used internally as a drink to improve eyesight from the inside and to boost the immune system."

"Results of tests on 96 human patients aged 60 years with senile cataract of varying degrees of maturity showed there was a profoundly beneficial effect on primary senile cataract, the effectiveness rate being 100 per cent with no side effects being found in the observed patients."

Jane Naish, who had originally written about her Irish Setter, reports "that after only three days treatment, her 'Blaze's vision has already improved dramatically. He can see things better at a distance as well as close up, his eyes themselves are brighter and, his owner reports, he is her own happy dog once more."
